My research interests are in developing computational methods and tools for applications in molecular simulations, nonlinear dynamics, and signal processing.

Molecular simulation
Structural and dynamic properties of solid-liquid interfaces
Calculating free energy of solid-liquid interfaces
Estimating thermodynamic errors of numerical integrators for molecular dynamics

Nonlinear dynamics
Methods for locating unstable periodic orbits in chaotic dynamical systems
Symbolic dynamics, generating partitions, and homoclinic tangencies in non-hyperbolic chaotic systems
Transition to chaos with multiple positive Lyapunov exponents (sometimes called "hyper-chaos")
Chaotic transitions in semiconductor lasers subject to delayed optical feedback

Measurements and data processing
Analog representation of a measurement process
Implementation of nonlinear filters for continuous measurement processes
